Recently, the ingredient propylene glycol has been in the news. We learned about this ingredient from Dr. Sean O'Keefe in a previous Best Food Facts post. Dr. O'Keefe said proplyene glycol is a colorless liquid that posesses a slight sweet taste. It's not antifreeze. Propylene glycol is classified by the FDA as GRAS, generally regarded as safe. Since propylene glycol is a GRAS compound, it is safe to use in foods.

We had some more questions about propylene glycol, so we reached out to Dr. O'Keefe for more information.

Certainly there's much to explore, so we sought out the professional opinions of several experts to get the whole story.

There is conversation aplenty about GMOs. In fact, there is so much talk of GMOs and GM foods that you may find it surprising to know there are only nine GM crops commercially available in the United States.
